This invention relates to new and useful port 3. An annular flange 11 is formed on improvements in valves and has for the prithe horizontal portiOn 8 of the spider 4 and mary object, the provision of a device of the has formed in its upper end a shoulder 12 above stated character which will be self on which is positioned a gasket or valve seat 5 closing or automatically closed by the pres- 13 and the latter is forced in engagement sure from the device to which the valve is atwith the shoulder 12 by a disk 1 L threaded tached, consequently assuring a leak-proof in the upper end of the flange 11. The disk valve and one requiring manual operation be- '14: isprovided with a suitable slot to receive fore the valve is open. 7 a screw-driver or similar instrument for 10 Another object of this invention is the prothreading the disk into and out of the flange 60 vision of a novel construction of valve or 11 as desired. i closing element and seat therefor which will I A closure element 15 including a stem v16 automatically seat itself and be further is slidably mounted in the opening 9 of the forced in engagement with the seat by the spider t and extends upwardly through 15 pressure from the device to which the valve alined openings formed in the gasket 13 and is applied and which is so designed that the disk 14: and has its lowerend engaged witha closing element or the seat may be easily recoil spring 17 mounted in the body as shown moved for repair when necessary. at 18 for the purpose of normally urging the A further object of this invention is the stem 16 upwardly and the disk 19 thereof in 29 provision of a valve of the above stated charengagement ''with the gasket, consequently '70 acter which willbe simple, durable and efficlosing the passage between the inlet port cient, and which may be manufactured and 2'and the outlet port 3. sold at a comparatively low cost. An annular neck 20 is formed on the body With these and other objects in view as will and is" of such a size that it willv permit the become more apparent as the description prodisk 14, gasket 13 and closure element 15 to 5 ceeds, the invention consists in certain novel be easily and quickly removed and replaced features of construction, combination and arthe bodywhen desired. A valve stem neck rangement of parts as will be hereinafter 21 isjt-hreaded into the neck 20. and is promore fully described and claimed. videdwithacentral bore provided with screw For a complete understanding of my inthreads to receive corresponding threads-22 Q vention,reference is to be had to the follow- .formed on a valve stem or operating meming description and accompanying drawings, ber 28,'thejlower,endof which is recessed or in which: substantially conical shape as shown at 24; Figure 1 is a vertical sectional view illuss to receive or engage the upper conical shaped trating a valve constructed in accordance end 25 of the stem 16.

A suitable hand wheel 28 numeral 1 indicates the body of a valve havis secured to the outer end of the member 23 ing oppositely disposed inlet and outlet inwhereby a person may easily rotate the memternally screw threaded ports 2 and 3 respecber 23 in either direction for the purpose tively separated by a spider l formed within of unseating the closure element 15 or to perthe body and which provides chambers 5 and mit the latter to automatically seat itself.

The spider t includes vertical portions In operation the valve is especially de- A 7 formed integrally with the body 1 and also signed for use in conjunction with an air a horizontal portion 8 provided with a censupply means and an air reservoir. Howtral opening 9 and a plurality of annularlyv ever the device is capable of other applica arranged openings 10 to permit air or liquid tions for controlling gas, or any other fluid.

to pass from the inlet port 2 to the outlet Acompressor is preferably connected to the outlet port 3 while the reservoir is connected to the inlet port 2 in any well known manner so that when the compressor is stopped, the closure element 15 automatically closes and cuts off the back pressure to the compressor. The closure element 15 is aided in moving to a closed position and held in such a position by the pressure from the reservoir connected to the inlet port 2.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described the invention, what 1 claim is:

1. A valve comprising a body, a wall in said body and having a passage, a flange on the wall about the passage, a valve seat removably secured to the flange, a closure element for the valve seat and normally urged in engagement therewith by the fluid pressure in the body, and a manually operated means to unseat the closure element.

2. A valve comprising a body, a wall in said body and having a passage, a flange formed on the wall about the passage, a gasket carried by the flange, a disk detachably securing the gasket to the flange and cooperating with the latter in forming a valve seat, a spring pressed closure element for the seat, and a manual control means carried by the body to disengage the closure element from the valve seat.

3. A valve comprising a body, a wall in said body and having a passage, a valve seat carried by the wall, a stud slidably mounted in the wall, tension means engaging the stud and the body, a disk carried by the stud I to engage the seat under the influence of the tension means and the pressure in the body, and a manually operated stem carried by the body to engage the stud to disengage the disk from the seat.

In testimony whereof I afiix my signature.
